.SH DESCRIPTION
.sp
.LP
The \fBin_wch()\fR and \fBwin_wch()\fR functions retrieve the complex character
and its rendition located at the current cursor position of the  \fBstdscr\fR
window and window \fIwin\fR, respectively. The \fBmvin_wch()\fR and
\fBmvwin_wch()\fR functions retrieve the complex character and its rendition
located at the position indicated by the \fIx\fR  (column) and \fIy\fR (row)
parameters (the former in the \fBstdscr\fR window; the latter in window
\fIwin\fR).
.sp
.LP
All these functions store the retrieved character and its rendition in the
object pointed to by \fIwcval\fR.
.SH PARAMETERS
